Source:
Ossian, IA — Castalia, IA
This side-by-side compares ZIP 52161 (Ossian, IA) and ZIP 52133 (Castalia, IA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies.

That difference in population size and density alone reshapes how every other metric should be interpreted — a higher-income ZIP with 1,200 residents behaves very differently from one with 45,000.
On income and education, ZIP 52161 reports a median household income of $87,870 against $76,250 in ZIP 52133, with per-capita income of $35,016 vs $34,992.
